It,s not a nice problem for us Farmers.I seen a study done once that had a section of a alfalfa field sectioned off.It was a 6ft by 6ft square section in a huge open field.The section was way out in the middle.The section had hay growin out of the top of the fence enclosure and the whole field was half the size of the section in height.That,s how much the Deer grazed the field.This was a university study.
